The utility model is characterized in that the miniature inverter comprises a multi-coat PCB (printed circuit board) which is stuck a large quantity of electronic components and an IPM (intelligent power module) which has equal area with the multi-coat PCB and integrates the entire desired circuits. The inverter is directly installed on the position of the connection box of the motor shell, is supplied power by an original direct current power supply, and makes use of the shell to dissipate heat; the IPM is used as the flat base of the main circuit of the miniature inverter; a control circuit is directly installed on the surface of the IPM; the integral driving device can be used for directly substituting an original direct current motor. The utility model can be directly applied to the auxiliary blower of the diesel locomotive of railway and small-sized electrical operated equipment whose power supply is provided by wind force.
Description
Technical field
The utility model relates to a kind of miniature inverter that is driven ac three-phase asynchronous motor by direct current supply, and and the integrated drive unit that combines of ac three-phase asynchronous motor, the small-sized electric equipment that this device can directly apply to the beeliner accessory fan and power supply is provided by wind power generation.
Background technology
At present, the accessory fan of beeliner substantially all is to use direct current machine, by the former DC power supply on the locomotive.And manyly provide the small-sized electric equipment of power supply also substantially all to be to use direct current machine by wind power generation.Because the inherent defect of the commutator rectifier of direct current machine, the problem that this mode exists is that maintenance workload is big, and the maintenance task is heavy.
Though once found the device have similar motor and inverter to combine abroad, because its inverter volume (account for motor volume 1/4) greatly, inverter must be installed in the anti-drive end of motor, occupies bigger installing space.Consequently: can not directly replace former direct current machine neatly, need on mounting structure and installing space, readjust.
Along with the development of power electronic technology and Semiconductor Converting Technology, emerge a lot of microdevices and advanced control technology at present.We can design the very miniature inverter of volume now, and making only needs simple original direct current machine of removing at the scene, just the miniature inverter and the three-phase AC asynchronous motor of integrated design can be installed directly in situ.This replacement notion is simple, economic, practical, and its core is the manufacturing technology of miniature inverter.Adopt multi-layer PCB (printed circuit board (PCB)), a large amount of Surface Mount miniature electronic components and parts, IPM (Intelligent Power Module) and present state-of-the-art miniature DSP (digital signal processor), representing the new height of Semiconductor Converting Technology development at present.
Summary of the invention
The purpose of this utility model is a kind of big or small like that miniature inverter of terminal box that has only motor of design, be directly installed on the position at the original terminal box place of threephase asynchronous machine and realize be electrically connected, the device after making motor and inverter integrated can not exceed the overall dimension of former direct current machine on overall dimension.
Technical solution of the present utility model is achieved in that a kind of miniature inverter, its structure is to comprise a multi-layer PCB (printed circuit board (PCB)) with a large amount of Surface Mount miniature electronic components and parts, area size equates with it the integrated IPM of whole required circuit (Intelligent Power Module) and multi-layer PCB is fixed on the IPM module by screw assembly, and make it the realization electrical connection.Described miniature inverter is installed on the terminal box position of threephase asynchronous, and realizes being electrically connected with threephase asynchronous machine, constitutes a kind of miniature inverter and threephase asynchronous integrated drive device that is driven by DC power supply.IPM module in the described miniature inverter is integrated two point form main circuit comprises switching device and the driving and the protective circuit of this drive unit of control that is useful on.PCB multilayer board in the described miniature inverter, have five road insulating power supplies, signal processing circuit, master control DSP and peripheral circuit thereof, pulse is isolated and a surging electric capacity, two terminals of input interface P, N insert DC power supply DC+, DC-respectively, output interface U, V, three terminals of W directly insert threephase asynchronous machine, and control circuit is then directly controlled IPM by 1～19 terminal.
Compared with prior art, the beneficial effects of the utility model are that can to solve the maintenance workload that present use direct current machine exists effectively big, and the problem that the maintenance task is heavy has very big economic and practical.
